UNITED STATES PATENT OEEIOE.

GEORGE DAVIS AND JOHN R. HOOVER, OE ELIZABETH PORT, NEW JERSEY.

IMPROVEMENT |N DRAWING-FRAMES FOR HEMP, aw.

Specification forming part of Letters Patent No. 106,130, dated August 9, 1870.

.To all 'whom it may concern:

Beit known that we, GEORGE DAVIS and JOHN R.HOOvER, of Elizabeth Port, in the county of Union and State of New Jersey,

' skilled `in the art toma-ke and use the same,

reference being had to the accompanying drawing, formingpart of this specification.

This invention relates to improvements in machinesfor drawing hemp; and consists in the peculiar construction and arrangement of the devices for that purpose, as hereinafter.

described.

Figure 1 is a longitudinal section of a drawing-frameconstructed according to our iinprovements, and Fig. 2is a plan view of the Similar letters of reference indicate corresponding parts. i

A represents theV rotary disks, and B the oscillating arms, carrying the comb-teeth C, and mounted in thelsaid disks so as to turn therein. These arms have cranks D at one or both ends, with pins E,`which engage in annular grooves Fin disks G, iiXed one at each end of the comb-cylinder, and set eccentrically thereto, as shown in the drawing, for causingy the arms Br to oscillate as they revolve, the

oscillation being caused by the crossing of the orbits of the pins Fand the arms B.

'The axles of the disks G, being set on the receiving side of the axis of the cylinder, will cause the teeth G, when ascending to enter the ber, as at I, to pitch forward, so as to stand nearly perpendicular to the line of thev fiber,l so as to enter in the most direct 'and easy manner--that is to say, endwise; and the `same arrangement ofthe disks causes the teeth to pitch backward at K in going down, so as to draw away from the ber, also in an endwise direction.

The improvement is applicable to machines for drawing other fibrous substances.

Having thus described our invention, what we claim' as new, and desire to secure by Letters Patent, is

The rotary disks A A and comb-bars B, provided with the cranks D E, in combination with the stationary grooved disks G G, placed eccentrically to the disks A, and all constructed and arranged as and for the purpose specified.

The above specification of our invention signed by us this 16th day of April," 1870.
